Exhaust and cat question

Hey,
I have a little problem can someone tell me where the cat is in the JK?
I have installed an new exhaust and now my Dealer told me i don't have a cat anymore, how i understood a cat back meant from cat and back or am I wrong?
On this forum I have read multiple times that the Jk's have a resonator and in the back the muffler.

Thanks for the help!

I have a Rugged Ridge cat back exhaust and I definately have cats. The JK cats are up front. You're not wrong. If you basically installed an exhaust from the rear axle back you definately have cats. It would be a process to remove the cats, you would know it. You don't have the original muffler or a resonator. Again, someone at a dealer who doesn't know what they're talking about.

Cat back means from cat and back right?
I have an afe Cat back high tuck, I think is the name.
Can you tell me where the cat is, is it in the pipe that is pretty much under the drivers seat? (I have a 2013 2 Door)

Thanks for the help!

Just do a quick Google search and look at images. You'll see not only where it's located, but actual pictures. Here's a diagram of your exhaust system....the cats are right near your engine...#5 in the diagram......can't miss them.

If I'm understanding the question correctly, a cat back doesn't include the cat. It means everything past the cat.

Yup-yup.....when they say "cat-back", it's starting just after the cat and replaces all the way back.

My guess is that your resonator isn't on your Jeep and your semi-informed dealer is confusing that with the cats.

The resonator sits horizontal to the ground in the single exhaust line, almost directly under the driver. It looks like a bullet muffler. It then feeds downstream, over the axles and into the muffler. The muffler sits directly under your rear cargo area and looks like a trashcan mounted sideways (it's about the size of a trashcan).

The cats are upstream of the resonator, one on each side. off the exhaust manifolds as shown in the diagram bfschor posted. They're a biatch to get to if you have to service them. Jeeps have two cats, one per side. Many of today's vehicles have four (two per side), upstream and downstream cats.

The picture below shows where I straight piped in place of my resonator. If you don't see what looks like a muffler where I've circled in red (your resonator) then it's been removed and the dealer is likely mistaking this for a cat.

The upside is that you've elminated a dealer from future servicings.

Most cat backs that you'll see are actually "axle" back systems which connect in the area of the rear axle, but they are definately far "back" of the cats. Some of the newer JK cat back systems probably include removing the resonator. My 10 didn't have one. The 3.6 engine does.
